Abstract

In this study, tendencies of wheel vibration related to curve squeal by parameters of a test rig were investigated with an analytical model. The analytical model for vibrations of both a railway wheel and rail was developed for prediction of squeal noise in the previous study. The wheel vibration obtained by the model had a good agreement with the measured vibration in the rig in the point of tendencies respect to the yaw angle and the rolling velocity. Features, that the wheel vibrations were increased considerably when the yaw angles became slight degrees from zero degrees and were also increased slowly respect to the angle above the slight degrees, were observed in the test rig. The analytical model simulated well these features. Although the disagreement of magnitude of wheel vibration remains, the model approximately simulates the vibration related to squeal noise.
